Out of convinience ?

I use no cd cracks if and only if I have a physical copy of the game. I hope that doesn't get me in trouble here.

I use them too nowadays, scratched too many CD´s to death before using cracks... :/

Greatest thing that ever happened to me was Galactic Battlegrounds coming here. My disc was so scratched to hell from over use I couldn't even install it anymore. :P

^This.

I pirated Manhunt after I bought it from GG, because the version those fuckers from Rockstar sell has a game-breaking bug that's been there for years, and they never bothered fixing it...

My store bought copy of Bioshock came with an incorrect activation code, so I simply cracked it.

it's cool bro, ur not in trouble with me.

I once dropped my Tekken 5 disk, I needed 5 attempts to pick it up...the disk was so scratched I couldnt get past the main screen.

I had the same problem with Quake 3 Arena (last digit missing). Fortunately there were key generators...

Not that I own any PC games on CD any more, but if I did I'd probably get no CD cracks for them. The convenience of not needing to change a CD to play a game is great.

Sometimes yes, just so that I don't have to insert the CD just in order to play. Quite often I still choose to play without cracks, just because I either can't be arsed to try to find a crack (the exact correct version etc.), or even that I don't simply find a working crack. That's why I say "bullshit" to those who say DRM or copy protection doesn't matter because you can always easily get a crack somewhere, Not always.

Or if there is an option to easily make a CD image of the game and play with it, that is fine too. This seems harder for Windows games (even the old ones like Heavy Gear etc.), while DOS era CD-games are very easy to "imaginaze", apparently they don't have much of any copy protection.

Sometimes it may even be to get the game running at all, like running Wheel Of Time on a virtualized (VMWare Player) Windows XP session, it didn't seem to like the game's copy protection (it complained the original CD was not in the CD drive even though it was, and it had even ran the installation from it ok) so I needed to use a noCD crack in order to get the game running there.

I do download cracks out of convenience for disc games, but it's usually no skin off my back if one isn't available.

Where these games have CD or DVD copy protection that doesn't work on modern PCs (e.g. StarForce, SafeDisc), cracks are almost essential. I do have a couple of games with non-functional copy protection on modern Windows versions with no crack available - I end up having to use an older Athlon 1800 with dual-boot Win98/WinXP for them.
I do the same with games running in DOSBox, especially as it's easy to mount the ISO in DOSBox. What were all the cop cars doing outside your hotel then?

Its not an actual game breaking bug. It was the last patch they implemented that broke the game. There was a good fix on Steam forums, don't know if its still there.

Yeah, I tried that one from the steam forums, didn't work...
